In a specific embodiment, as shown in fig. 1, the tower body 1, the frustum 2 and the cylinder 4 are all arranged in the up-down direction; the tower comprises a tower body 1, a tower body 2, a partition plate 3, a barrel 4 and a back washing opening 40, wherein a closed arc-shaped cover is arranged above the tower body 1, the lower part of the tower body 1 is fixedly connected with a large-diameter port 21 of the frustum 2, a small-diameter port 22 is covered by the partition plate 3, the lower part of the partition plate 3 is the barrel 4, and the lower end of the barrel 4 is provided with the back washing opening 40.
The partition 3 is provided with a plurality of water caps 31, the water caps 31 allow fluid to pass but not resin, so that the polishing resin entering the separation tower from the material inlet 11 is gathered above the partition 3, water entering the separation tower from the water inlet 13 can enter the cylinder through the partition 3, and when fluid such as alkali liquor, water, carbon dioxide and the like is injected into the cylinder 4 through the backwashing port 40, the fluid can pass through the partition 3 to enter above the partition 3 and contact with the polishing resin. As can be easily understood, the number and the position distribution of the water caps 31 can be adaptively adjusted according to the size of the partition plate 3; specifically, as shown in fig. 2, when the fluid is a liquid such as an alkali solution and/or pure water, in order to ensure that the liquid can uniformly flow through the polishing resin, the water caps 31 need to be uniformly distributed on the partition plate 3, and the water caps 31 may be circularly distributed on a plurality of concentric circles according to the shape of the partition plate 3. At the moment, when the liquid in the cylinder 4 contacts with the materials through the partition plate 3, the liquid can be uniformly distributed, and the phenomenon that the water flow is not uniform when the liquid flows through the polishing resin is avoided.
More preferably, the water inlet 13, the material inlet 11 and the material outlet 12 are all disposed on the side wall of the tower body 1, wherein the water inlet 13 and the material inlet 11 are all disposed above the side wall of the tower body 1, and the material outlet 12 is disposed below the side wall of the tower body 1. At this time, the polishing resin entering from the material inlet port 11 falls downward by gravity and is accumulated above the partition plate 3.
The second material discharge pipe 122 includes at least one branched pipe, and the number and shape of the branched pipes in the second material discharge pipe 122 are not limited in this application, and the specific number and shape may be adaptively adjusted according to the process of separating the polishing resin. Since one end of any of the branch pipes is connected to the second end 124 of the first material discharge pipe 121 and the other end of the branch pipe extends toward the partition plate 3 and has a gap a with the partition plate 3, the polishing resin gathered above the partition plate 3 can enter the second material discharge pipe 122 through the gap a and be discharged out of the tower body 1 through the first material discharge pipe 121. In one embodiment, the second material discharging pipe 122 includes a branch pipe, one end of the branch pipe is connected to the second end 124, and the second material discharging pipe 122 is communicated with the first material discharging pipe 121, so that the material in the second material discharging pipe 122 can enter the first material discharging pipe 121 and then be discharged out of the separation tower. In another embodiment, as shown in fig. 3, the second material discharging pipe 122 includes four branch pipes, and one end of each branch pipe is fixedly connected to the second end 124, so that the positive resin can simultaneously enter the first material discharging pipe 121 from the four branch pipes, which is highly efficient in discharging the positive resin. In other embodiments, the second material discharge pipe 122 may be two symmetrically arranged branch pipes, and the arrangement and the function of the second material discharge pipe 122 are similar to those of the four branch pipes in the above embodiments, so detailed descriptions thereof are omitted.
When the polishing resin is separated, a pneumatic diaphragm pump is adopted to pump the polishing resin added with a proper amount of water into the tower body 1 from the material inlet 11, the polishing resin falls on the partition plate 3 under the action of gravity, at the moment, a layering agent is injected into the tower through the backwashing port 40, the layering agent is contacted with the polishing resin on the partition plate 3 through the partition plate 3, the negative resin and the positive resin in the polishing resin are promoted to be layered, and then the positive resin gradually falls to the lower part of the negative resin. The delaminating agent may be suitably adjusted according to the kind of the polishing resin, and for example, the delaminating agent may be pure water or an alkali solution. After the layering of the male resin and the female resin is completed, the male resin below can enter the second material discharge pipe at the moment because one end of the second material discharge pipe is close to the partition plate and is at a distance A from the partition plate. At this time, pure water is continuously injected into the tower through the water inlet 13 and the backwashing port 40, so that the lower positive resin continuously enters the second material discharge pipe 122 through the gap a and further enters the first material discharge pipe 121, and the positive resin can be discharged out of the tower body 1 and transferred to a positive resin regeneration device for regeneration; after the positive resin is discharged, a small amount of mixed resin at the layered interface of the positive resin and the negative resin can be discharged out of the tower body and put in a mixed resin storage device to wait for the separation of the next batch; the negative resin is left in the tower 1 to be regenerated. And (2) carrying out acid regeneration treatment on the positive resin discharged out of the tower body 1 and carrying out alkali regeneration treatment on the negative resin remained in the tower body, so that the positive resin and the negative resin recover the ion exchange performance, namely, the positive resin and the negative resin are regenerated.
Further, the second material discharge pipe 122 includes four branch pipes, and the four branch pipes are distributed in a trumpet shape.
